Sonochemical synthesis of Dy-doped ZnO nanostructures and their photocatalytic properties

Sonochemical synthesis of Dy-doped ZnO nanostructures and their photocatalytic properties

Dy-doped ZnO nanostructures were synthesized by a sonochemical method. The concentration effect of Dy on their phase, morphology, optical properties and photocatalytic activities was investigated. XRD patterns indicated that the as-synthesized 0-3% Dy-doped ZnO was hexagonal wurtzite structure. SEM...
